This invention relates to closures for bottles and other receptacles adapted to contain liquids particularly alcoholic beverages, liquors or perfumes.

An object of the invention is to provide a closure permitting free discharge of the liquid contained in the receptacle in a continuous and uninterrupted manner until all of the fluid has been dispensed but which at the same time will prevent the introduction of liquid into the receptacle through the closure.

Further features and objects of the invention will be more apparent to those skilled in the art upon a consideration of the accompanying drawing and the following description wherein an exemplary embodiment of the invention is disclosed,

In the drawing:

Figure l is a vertical sectional view showing the component parts of the closure arranged on the neck of a bottle.

Fig. 2 is a perspective view of a ring-shaped member providing a seat for the valve.

Fig. 3 is a plan view of the valve disk.

Fig. 4 is a sectional View of an inner cap member for housing the valve actuating means.

As illustrated in the drawing the closure comprises a ring-shaped member L which fits into the mouth of the bottle and is provided with a lateral flange L which is adapted to fit over the upper edge of the bottle neck. A rubber or cork washer M may be interposed between the flange L and the end of the bottle neck.

The closing and opening of the passageway to the interior of the bottle or receptacle is controlled by a disk-shaped valve having the lower face thereof covered by a semi-soft rubber layer K vulcanized to the disk K. The periphery of the composite valve disk is preferably tapered as illustrated in Fig. l to provide a truncated coneshaped disk with the base facing towards the interior of the bottle. The valve is provided with a guide rod Q secured adjacent the center thereof and extending perpendicularly from the disk and passing through a hole N in a bracket The bracket 0 is secured to the depending portion of the ring member L and the guide rod Q maintains the valve in a central position so as to prevent lateral vibration thereof but permitting free upward and downward movement.

The opening movement of the valve K is limited by three abutments I provided on the lower part of a float G which is arranged immediately above the valve and the float consists of a cylindrical shaped sealed hollow member. The upward movement of the float G is limited by means of an inner cap member E which includes a circular depending sldrt adapted to engage the top face of the flange L. The lower portion of the skirt is provided with openings S so that the liquid of the receptacle may pass therethrough. The interior of the cap member E i provided with circumferentially spaced ribs H which limit lateral movement of the float G. The top portion of the cap member E is provided with a spherical shaped portion E as illustrated in Figs. 1 and 4. A plurality of balls or spheres F are arranged between the top surface of the float G and the spherical portion E of the cap member so as to form an arrangement in which the float G is permitted to move upwardly so as to regulate the outlet of liquid through the opening in the ring member L.

The flange L is provided with an upstanding ring J so as to surround the disk-shaped valve K in a spaced relation thus providing a small concentric space through which the liquid contained in the receptacle is discharged when the bottle is inclined. In other words the liquid exerts pressure against the lower face of the disk K so as to cause opening thereof and movement of the liquid from the bottle in a continuous manner since a continuous draft of air is established to the inside of the receptacle.

An outer cap member D is provided for protesting the inner parts of the closure and comprises a bell-shaped body provided at its lower end with a rim portion T adapted to surround the flange L and cover the end portion of the bottle neck. The opposit end of the outer cap member D is provided with an opening A for the discharge of the liquid and this end of the capmember is provided with a threaded projection for receiving a threaded cover U. The outer cap member D is provided adjacent the threaded projection with an annular groove B for receiving pins C secured to the spherical portion E of the inner cap member E. The groove B provides a reduced section in the outer cap member which acts as a safety feature so that in case a tool is inserted for forcing the valve open to introduce liquid into the receptacle this pressure may produce breakage of the cap member D along the groove B.

The outer cap member D holds the inner cap member E in position by means of the pins C and. all parts of the closure may thus be securely attached to the bottle by means of a metal band or seal engaging the ring T and an annular engagement of the bottle neck. When the rim T of the outer cap member is secured to the neck of the bottle it is impossible to introduce liquid into the receptacle since the balls F acting on the float G force the disk K against the valve seat in the absence of pressure exerted on the lower face thereof and liquid cannot be introduced into the bottle. The inner cap member E further prevents the introduction of any tool or the like through the opening A to disturb the normal position of the valve or float.

When liquid in the receptacle or bottle is to be discharged the liquid exerts a pressure on the valve to raise the float member and liquid escapes over the flange J and through the openings S into the outer cap member D from which position the liquid may pass to the exterior through the opening A.

While the invention has been described by reference to specific structural details it is apparent that changes may be made therein. Such modifications may be made Without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim:

1. A non-refillable stopper for a bottle comprising, a ring member adapted to be inserted in the bottle neck, an annular flange carried by said ring member extending laterally over the edge of the bottle neck, a disk valve having a rubber face adapted to seat on said ring member, an inner cap member having an apertured skirt resting on said annular flange and a spherical shaped portion, a float within said inner cap member engaging said disk valve, 2, plurality of balls loosely arranged above said float within the spherical portion of said inner cap member, an outer cap member covering said inner cap member and spaced therefrom, a rim carried by the outer cap member embracing said flange and the bottle neck and adapted to be secured to the bottle, said outer cap member having an outlet opening therein and a groove surrounding the opening reducing the strength of the outer cap member, and pins between said inner cap member and the outer cap member extending into said groove for holding the inner cap member against said flange.

2. A non-refillable stopper for a bottle comprising, a ring member adapted to be inserted in the bottle neck, an annular flange carried by said ring member extending laterally over the edge of the bottle neck, a disk valve having a rubber face adapted to seat on said ring member, an inner cap member having an apertured skirt resting on said annular flange and a spherical shaped portion, a sealed cylindrical shaped float within said inner cap member having projections engaging said disk valve, a plurality of balls loosely arranged above said float and retained within the spherical portion of said inner cap member by said float, an outer bell shaped cap member covering said inner cap member and spaced therefrom, a rim carried by the outer cap member engaging said flange and adapted to be secured to the bottle, said outer cap member having an outlet opening in the top portion thereof and an annular groove surrounding said opening reducing the thickness of the outer cap member adjacent said opening, and pins carried by the inner cap member engaging the outer cap member in said groove for holding the inner cap member against said flange.
